Guide to the Secure Configuration of SUSE Linux Enterprise 12

with profile DISA STIG for SUSE Linux Enterprise 12
This profile contains configuration checks that align to the DISA STIG for SUSE Linux Enterprise 12 V1R2.
This guide presents a catalog of security-relevant configuration settings for SUSE Linux Enterprise 12. It is a rendering of content structured in the eXtensible Configuration Checklist Description Format (XCCDF) in order to support security automation. The SCAP content is is available in the scap-security-guide package which is developed at https://www.open-scap.org/security-policies/scap-security-guide.

Providing system administrators with such guidance informs them how to securely configure systems under their control in a variety of network roles. Policy makers and baseline creators can use this catalog of settings, with its associated references to higher-level security control catalogs, in order to assist them in security baseline creation. This guide is a catalog, not a checklist, and satisfaction of every item is not likely to be possible or sensible in many operational scenarios. However, the XCCDF format enables granular selection and adjustment of settings, and their association with OVAL and OCIL content provides an automated checking capability. Transformations of this document, and its associated automated checking content, are capable of providing baselines that meet a diverse set of policy objectives. Some example XCCDF Profiles, which are selections of items that form checklists and can be used as baselines, are available with this guide. They can be processed, in an automated fashion, with tools that support the Security Content Automation Protocol (SCAP). The DISA STIG, which provides required settings for US Department of Defense systems, is one example of a baseline created from this guidance.
Do not attempt to implement any of the settings in this guide without first testing them in a non-operational environment. The creators of this guidance assume no responsibility whatsoever for its use by other parties, and makes no guarantees, expressed or implied, about its quality, reliability, or any other characteristic.

Checklist

Group   Guide to the Secure Configuration of SUSE Linux Enterprise 12   Group contains 4 groups and 1 rule
Group   System Settings   Group contains 3 groups and 1 rule

[ref]   Contains rules that check correct system settings.

Group   Installing and Maintaining Software   Group contains 2 groups and 1 rule

[ref]   The following sections contain information on security-relevant choices during the initial operating system installation process and the setup of software updates.

Group   System and Software Integrity   Group contains 1 group and 1 rule

[ref]   System and software integrity can be gained by installing antivirus, increasing system encryption strength with FIPS, verifying installed software, enabling SELinux, installing an Intrusion Prevention System, etc. However, installing or enabling integrity checking tools cannot prevent intrusions, but they can detect that an intrusion may have occurred. Requirements for integrity checking may be highly dependent on the environment in which the system will be used. Snapshot-based approaches such as AIDE may induce considerable overhead in the presence of frequent software updates.

Group   Operating System Vendor Support and Certification   Group contains 1 rule

[ref]   The assurance of a vendor to provide operating system support and maintenance for their product is an important criterion to ensure product stability and security over the life of the product. A certified product that follows the necessary standards and government certification requirements guarantees that known software vulnerabilities will be remediated, and proper guidance for protecting and securing the operating system will be given.

Rule   The Installed Operating System Is Vendor Supported   [ref]

The installed operating system must be maintained by a vendor. SUSE Linux Enterprise is supported by SUSE. As the SUSE Linux Enterprise vendor, SUSE is responsible for providing security patches.

Warning:  There is no remediation besides switching to a different operating system.
Rationale:

An operating system is considered "supported" if the vendor continues to provide security patches for the product. With an unsupported release, it will not be possible to resolve any security issue discovered in the system software.

Severity: 
high
